The three greatest QBs of the past decade (Manning, Brady, and Brees) have not had cannon arms or great mobility. I think you are looking for the wrong things in a QB. Nick Foles' physical abilities are fine.

No, you're just misinterpreting what I'm saying. Zona summed it up pretty well in the post above. I wasn't being critical of Foles, in fact to the contrary. And I think if you read my post more carefully you'll see that. I'm just saying that he isn't an elite physical talent like Luck, but he makes up for it by being a heady football player.
